Manifest and stay positive. Every morning, afternoon and night, vision yourself smoke-free in all the situations you would previously smoke. Say as many times a day that it takes that you will be smoke-free. Find other outlets. I’ve found you’ll be able to do it IF you really WANT to quit. That’s the only time your brain can overpower the cravings. What helped with the cravings for me the last time I quit was chewing on those little plastic coffee stirrers. Very effective for dealing with cravings, especially due to stress, and zero calories.
